当我尝试将XML加载到ClassPathXmlApplicationContext时，控制台出现错误提示。

org.springframework.context.support.AbstractApplicationContext prepareRefresh

如果我从XML删除util：list标记，则可以正常工作，但是这样做却给我一个错误。我想将依赖项注入到集合类型Vector中。这是我的XML。还会出现编译时错误“ cvc-complex-type.2.4.c：匹配的通配符是严格的，但是找不到元素'util：list”的声明。

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:util="http://springframework.org/schema/util"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
    http://springframework.org/schema/util 
    http://www.springframework.org/schema/util/spring-util-3.1.xsd">
    <bean class="Beans.PerticularCollection" id="pc">
        <property name="names">
            <util:list list-class="java.util.Vector">
                <value>Devang</value>
                <value>Foram</value>
            </util:list>
        </property>
    </bean>
</beans>

您可以尝试以下吗？

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
..
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="
...
http://www.springframework.org/schema/util 
        http://www.springframework.org/schema/util/spring-util.xsd">
...
</beans>

理想情况下，建议在不指定版本的情况下使用XSD。默认情况下映射最新版本。请参阅E.2.2 The util schema部分here

cvc-complex-type.2.4.c：匹配的通配符很严格，但是找不到元素'util：list的声明
